Despite her old feelings for Gwindor, Finduilas fell in love with Túrin. Túrin failed to notice her feelings, she reminding him of Lalaith, the sister he lost in childhood. Gwindor realized that Finduilas had fallen in love with Turin, and revealed his name to her in an attempt to discourage her pursuit.[1]

At the sack of Nargothrond by Glaurung, Gwindor was slain and Túrin was entranced by the dragon. Because of the enchantment, he could not hear Finduilas' cries as she was being dragged past him by the Orcs as a captive for Angband.[4]

Due to Glaurung's deceit Túrin abandoned Finduilas and instead went to Hithlum in search for his kin, and by the time he regained his senses she had been killed. When the Orcs were waylaid by the Haladin of Brethil at the Crossings of Teiglin they killed all their captives, pinning Finduilas to a tree with a spear. The Haladin buried her in a mound they called Haudh-en-Elleth ("Mound of the Elf-maiden").[5]
